Took me about 12 attempts to reset it using the battery removal method; it finally worked.
It seems the Flic Mac client app is essentially pointless now, right? After upgrading to Big Sur today, the Flic app works... but widgets are now gone and can't be added back. Is this something Devs are aware of, or are we just going to say the Flic Mac Client only works with Catalina and below?
Edit: To be more specific, I mean the Flic widget is now gone from the "Widgets" pane of the Mac. My existing "widgets" inside of the Flic app are still there after the OS update, but of course, completely pointless. I have to go into edit mode on the widget and then click "execute" to use them. I can find no other way to trigger them.
BUMP - widgets are no longer appearing in the Notification Center.
